This was a minimal release made solely for the purpose of pushing out a single specific bug fix.
Fix bug that caused toolchain path properties to not be populated
arduino/arduino-cli#1867, arduino/arduino-ide#1411
Under certain uncommon platform installation conditions, the properties defining paths to the tools used for compiling, uploading, burning bootloader for boards of that platform were not automatically generated by the Arduino build system.
Fix bug that caused leading zeros to be stripped from Serial Monitor timestamps
Previously, Serial Monitor timestamps used a non-standard format not compliant with ISO 8601, where hour or minute values less than 10 did not have a leading zero.
